1. Making Welding Groove in Steel Plate Flat Butt Welding Machine:

1) Necessity: For steel plates with thickness higher than 15mm, welding grooves needs to be made on its edges before joint welding, to get ideal joining effect;

2) This can be made with the triple flame cutting system, installed at incoming side of steel Plate Butt Joint Machine gantry beam;
 

2. Critical: Melt-Thru Welding Unit in Sheet Steel Plate Butt Joint Machine:

1) Importance: This is the central working element in Steel Plate Butt Joint Welding Machine, fulfilling superior quality single side plate joining;
2) Welding Modes: Based on thickness of steel plates for joining, it can be either large current SAW submerged arc welding, or smaller current CO₂ gas shielded welding;
 

3. Supplementary Function Units in Sheet Steel Plate Butt Joint Machine:

1) These include all the supporting function cells equipped in the Plate Flat Butt Welding Machine:
2) Such as: Welding power supply/ hydraulic system for steel plates clamp/ Cooling water recycling and refilling tank/ SAW welding flux recycling system, etc.

Wuxi JACK Patent Melt-Thru Technology in MP Series Flat Butt Welding Machine:

1. Copper Block Pad in Central Welding Unit of Steel Plate Butt Joint Machine:

1) The 1^st Photo: Copper has good thermal conductivity, which can dissipate heating generated during SAW quickly;

2) As shown in this photo, there are 2 arrays of through holes, machined at lateral sides of the copper pads;
3) Through these through holes, water tubes go through internal side of the copper pads, forming a closed loop circulation;
4) During melt thru butt welding in the Plate Butt Joint Welding Machine, running water flows inside the water tubes, quickly taking away welding heat;

2. Hydraulic Drive Clamping Blocks for Tightening Steel Plates Firmly in Flat Butt Welding Machine:

1) The 2^nd Photo: This photo reflects on the next step in assembly of melt thru welding unit, in the steel Flat Butt Welding Machine:
2) The black color block right above the copper pads, is used for pressing tightly steel plates to be joint, in the MP models Plate Butt Joint Machine;
3) There are grounding cables assembled onto these pressing blocks;

1. Models and Structure of MP Steel Plate Flat Butt Welding Machine:

a) There is only one type of Steel Plate Butt Joint Welding Machine, with stationary mechanical main frame, incorporating both beveling and joint welding function units;
b) Difference among models of Flat Butt Welding Machine lies in below three aspects:

1) Max. Valid Joint Welding Seam Width available from the Steel Plate Butt Joint Machine:

a) Range: From the smallest specification 2000mm (MP20) to the largest specification 5000mm (MP50) Flat Butt Welder;
b) Tailor Made: Any max. metal plate width within this range (2000mm to 5000mm) is available for being special made into steel Plate Butt Joint Welding Machine;
c) Variation: Usually model of the Flat Butt Welder differs on 500mm interval;

2) Available Welding Modes in the Steel Plate Butt Joint Machine:

a) SAW: For joining medium to large thickness (8mm~ 40mm) steel plates, it should be SAW (Submerged arc welding) in the Flat Butt Welder;
b) SAW takes mainstream application in the melt-thru welding mode of the MP models Flat Butt Welding Machine;
c) Joining small thickness plate: As complement, there is small welding current CO₂ GMAW for joining small thickness (3mm ~ 8mm) steel plates in Flat Butt Welding Machine. This takes supplementary position in application of the steel Plate Butt Joint Machine;

3) Optional Triple Flame Cutting for Selection in the Steel Plate Butt Joint Machine:

a) When Applicable: If steel plates thickness in the range of 15mm to 40mm, slant edge beveling should be made on edge of steel plate, ahead of melt-thru joint welding in the Flat Butt Welding Machine;
b) Reason on Beveling: This is for getting fully penetration welding effect on medium to thickness sheet metal plate;
c) Beveling Way: For application of steel Plate Butt Joint Welding Machine, beveling can be acquired either with flame triple cutting, or mechanical Edge Milling Machine;
d) Recommended Configuration: For the purpose of compact layout and flexible operation, majority applying cases have this optional flame triple cutting unit equipped in the Flat Butt Welder, installed at the incoming side of Plate Butt Joint Machine mechanical main frame.
